Abstract
PURPOSE: To obtain a wave detection output with good S/N and to make easy the design of gain sharing in each stage amplifying circuit, by cascade connection of a plurality of amplifying circuits in AC coupling through AC coupling.
CONSTITUTION: Stages of a plurality of amplifying circuits 3a∼3c constituting a video intermediate frequency amplifier are coupled with capacitors 10a, 10b for AC coupling. Thus, the low frequency component of input noise included in the video intermediate frequency signal inputted from an input terminal 1 is attenuated at the amplifiers of capacitor coupling to improve the S/N of wave-detected output, and the bias voltage of the amplifying circuits of each stage can be set independently, allowing to make easy the design of gain sharing.
